Improving Conceptions in Analytical Chemistry: ci Vi = cf VfMargarita Rodríguez-López and Arnaldo Carrasquillo Jr.A common misconception related to analytical chemistry, which may be generalized as the failure to recognize and to account analytically for changes in substance density, is discussed. A cautionary example is made through the use of mass-based units of composition during volumetric dilution. The correct application of the volumetric dilution equation ci Vi = cf Vf is discussed. A quantitative description of the systematic error introduced by incorrect use of the volumetric dilution equation is also specified. Rodríguez-López, Margarita; Carrasquillo, Arnaldo, Jr. J. Chem. Educ.2005, 82, 1327.

The chemical equation. Part I: Simple reactionsKolb, DorisA chemical equation is often misunderstood by students as an "equation" that is used in chemistry. However, a more accurate description is that it is a concise statement describing a chemical reaction expressed in chemical symbolism.Kolb, Doris J. Chem. Educ.1978, 55, 184.
